will possess durability, simplicity and inexpensiveness.

jections formed My invention com rises an outer receptacle of annular or other suitable shape provided with convexo-concave beads or proin the wall thereof, and projecting beyond its inner surface near to the top of the vessel. Removably mounted and centrally arranged within this outer receptacle is an inner receptacle which is spaced from the outer receptacle and provided at the bottom with a downwardly flaring peripheral skirt or flange of the same area, approximately, as and occupying the space between the receptacles and adapted to rest on the beads or projections of the outer receptacle for the purpose of supporting the inner receptacle in elevated osition; the skirt or flan e being also provided with peripheral notc es to enable the skirt or flange to pass I the beads or projections and rest in normal vanized iron, etc.,

of the outer receptacle.

or lowered position on the bottom of the outer receptacle.

I will now describe my invention with reference to the accompanying drawings and then point out the distinctive features thereof in the annexed claims.

Figure 1 is a vertical section of my improved vessel showing the inner receptacle in normal or lowered position. zontal section on the line A B of Fig. 1. Fig. 3 shows the inner receptacle in raised position and resting on the beads or projections Fi s. 4 and 5 are horizontal sections of an el iptical or oval shaped vessel showing the inner receptacle in normal or lowered and raised positions respectively.

The outer receptacle 0 may be made of any suitable material, such as sheet or galin annular or other desired form. Formed in the wall and projecting beyond the inner surface of. the outer re- Fig. 2 is a'horiceptacle a are a plurality of beads or projections g, of convexo-concave form.

I) is a removable inner receptacle of smaller diameter than the outer receptacle a which is centrally positioned within the outer receptacle a and is rovided with a perforated convexo-concave ottom c.

Projecting downwardly from thebottom of the inner receptacle 1) is a peripheral flaring skirt or flange f of the same area, approximately, as and occupying the space between the outer and inner receptacles and provided with'notches h, corresponding m number with and slightly larger than the beads or projections g. The outer receptacle a is provided with handles (1 for transportation purposes.

6 are handles secured to the inner receptacle b by means of which the same is raised or lowered. The inner receptacle b may be rovided with a cover or lid if desired.

, It will be observed that it will be impossible to withdraw the inner receptacle from the outer receptacle unless the inner receptacle is revolved until the notches in the skirt or flange register with the beads or pro- 'ections g. After raising the inner receptacle b above the beads or projections, the inner receptacle may be again revolved to throw the notches out of register with the beads or projections which will then engage the flange and support the inner receptacle. When in raised position the flange will form a cover or closure so that only an inconsiderable quantity of heat will escape from the outer receptacle. This insures a uniform temperature within the outer receptacle at all times.

When an irregular shaped vessel is employed the notches are located in the flange in proximity to the beads or projections which are located at diflerent distances from the ends of the outer receptacle so that a slight rotary movement of the inner receptacle changing it end for end will throw the notches into or out of register with the beads or projections. In a vessel of annular form it is desirable to have the beads or projections located diametrically opposite each other.

My invention is not limited to cooking vessels but the vessel may be constructed for sterilizing-surgical instruments, pasteurizingl, and similar purposes.

he inner receptacle is spaced from the outer receptacle by the peripheral downwardl flaring skirt or flange so that a water cham er is provided between the inner receptacle and' the outer receptacle. The perforated bottom of the inner receptacle being of convexo-concave shape its central part is in a position contiguous to the bottom of the vessel.

What I claim as new therein and desire to I secure by Letters Patent is:

having convexo-concave inward] 1. A vessel comprising an outer receptacle having projections on the inner side/of the wall ad acent to the top thereof, and an inner receptacle, centrally positioned within and spaced from the outer receptacle and provided with a peripheral flange located at the bottom thereof and of the same area, ap-

proximately, as and occupying the space beand inner receptacles,

tween the outer whereby it is-sup orted on the projections in raised position, the peripheral flange having notches in it in positions which correspond to the projections so thatin certain relative positions of the two receptacles the notches register with the projectlons and enable the in ner vessel to 1pass the projections.

2; A vesse comprising an outer receptacle ing projections formed in'the'wal adjacent to the top thereof, and an inner receptacle,

.centrally positioned within and spaced from the outer receptaclevand provided with a pcripheral flange located at the bottom thereof andof the same area, approximately, asand occupying the space between the outer and irlrner receptacles, whereby it is supported on t e ripheral flange having notches in it in positions which correspond to the projections so that in certain relative positions of the two receptacles the notches register with'the projections and enable the inner vessel to pass the projections.

extend- I tacles, whereby projections in raised position, the peed with adownwardly flaring periphthe pro ections in raised position, the peripheral flange having notches in it inpositions which correspond to the projections so that in certain relative positions of the two receptacles the notches register with the projections and enable the inner vessel to pass the projections.

.4. A vessel comprising an outer receptacle havi convexo-concave inwardly extending pro ections formed in the wall adjacent to t tacle, centrally positioned within and spaced from the outer receptacleand provided with a downwardly flan peripheral flange located at the-bottom t ereof and-of the same area, approximately, as and occupying the e top thereof, and an inner recepspace :between the outer'andinner recepit is supported on jections inraised position, the peripheral flange having notches in it in positlons which correspond to the projections so that in certain relative positlons of the two receptacles the notches register with the projections and the pro-;

enable the inner vessel to pass the projecv tions. I

In testimony whereof I hereunto affix my signature in presence of two witnesses.
